FURNACE FOR HEATING SOLDERlNG-COPPERS.

SPECIFICATION forming part of Letters Patent No. 229,935, dated July 13, 1880.

Application filed December 15, 1879.

To all whom it may concern:

Be it known that we, WM. G. ALEXANDER and GEORGE A. WVELLS, of Oskaloosa, in the county of Mahaska and State of Iowa, have invented certain new and useful Improvements in Furnaces for Heating Soldering-Coppers; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure] is an elevation, partly in section, of our improved device for heating soldering-coppers and for other purposes, showing a reservoir for containing gasoline or other liquids to be converted into gas, a pipe for conducting the liquid to a retort, a retort in which the gas is made, a pipe for conducting the gas to the burner, a cage for receiving the gas, a furnace or fire-pot in which the coppers are heated, a chamber for receiving the heat of the flame after it has passed the point where the coppers are heated and for utilizing such heat in the heating of a room or for any other purpose to which it is applicable, a case for inclosing the burner, the cage, and furnace, and a reservoir for the reception of gas for heating a room and for starting the operation of the device. Fig. 2 is a transverse section, showing the cage, the adjustable casing, the furnace, and the heat-reservoir above it. Fig. 3 is a horizontal section, showing the permanent casing around the cage and the adjustable covering for the regulation of the admission of air for the support of combustion; and Fig. 4 is a detached view, partly in section, showing a portion of the pipe that conducts the gas to the cage, a reservoir for said gas, and the removable discharge-tube.

Corresponding letters denote like parts in all of the figures.

This invention relates to that type of furnaces or fire-pots which are used for heating coppers or irons used in soldering together sheets or pieces of tin and other metals; and

it consists in combining, in an implement for such purpose, and for others to which it may be applicable, a reservoir for containing gasoline or any other liquid substance which is readily converted into gas by the application of heat, pipes for conducting the liquid to a retort and the gas from the retort to the cage, a cage for conducting the gas from the removable discharge-tube to the point of ignition, and a furnace for receiving the soldering-coppers or other substances while being heated; and it further consists in combining, with a reservoir for gasoline or other liquids, suitable pipes for conducting the liquid and the gas generated therefrom, a retort in which the liquid is converted into gas, and a reservoir for gas, arranged as hereinafter described, whereby it is made to contain gas which may be used for illuminating purposes and for burning in the commencing of the operation, all as will be more fully described hereinafter.

In constructing our improved implements, with a view of making them perfectly portable, and at the same time preventing them from being easily upset or otherwise deranged, we prefer to place the parts upon a platform, A, which may be of any desired dimensions. At any suitable point upon this form we secure a standard, A, of any form and height that will secure in position a pipe, A through which the liquid substance from which gas is generated passes from an elevated reservoir, A placed upon its outer end at such a height as to cause the substance which it contains to flow through pipe A to a retort, A where, owing to the fact that the latter is located above the point where the gas is burned and in the path of the flame, it is converted into gas, which passes through pipe A and into pipe A and on to the chamber or reservoir A and out through the removable discharge'tube A Surrounding the reservoir and tube last named there is a cage, B, the lower portion, B, of which is conical in form, and is perforated with small holes for the admission of air, which mingles with the gas passing through the tube A and is conducted by the imperforated portion B of the cage tothe upper perforated portion, B, the upper surface of which is fiat and supplied with perforations where the gas is ignited. This upper portion is made of thin sheet copper or brass, and has a large number of very small holes in it, or it may be made of fine wire-gauze made of copper, brass, or some other non-corrosive substance; but in either case it will be found to prevent the flame from descending to the lower portion of the cage, and will keep it at the top thereof, where it will be most effectual in heating the substances which may be placed in the furnace.

The cage above alluded to is surrounded by a casing, O, of sheet or other metal, which is secured to the platform A, and has in it a series of apertures, O G, as shown in Figs. 1, 2, and 3 of the drawings, for the admission of air to its interior.

Surrounding the casing O is a 'ring, D, of metal, which is also supplied with apertures which correspond in size and shape with those in the casing 0, upon which the ring D turns and by which the amount of air which is allowed to enter the case 0 can be regulated or entirely shut off at pleasure.

Owing to the fact that the pipe A which conducts the liquid to the retort, has in it a valve or cock, A for regulating the amount of material which is allowed to flow into the retort, it is apparent that the amount of gas generated in any given period of time can be controlled, and it is also-apparent that by the use of the ring D the amount of air-entering the implement can be regulated to correspond with the amount required for the support of the combustion of the differing amounts of gas.

Immediately above the upper end of the cage there is placed a furnace, E, its lower surface being supplied with grates, upon which the soldering-coppers or other substances rest while being heated, the spaces between said grates being of sufficient. area to allow the heated air to pass freely upward.

For convenience in passing the eoppers and other substances into the furnace and in removing them therefrom there is formed one or more double doors, I F, they being arranged one above the other, as shown in Fig. 1 of the drawings. The upper one of these doors is hinged to the casing F of the'furnace,'and the lower one to the lower edge'of the upper one, in order that said lower one may be opened and closed without changing the position of the upper.

When it is desired to use this implement for heating a room, or for heating any substance that may be placed upon it, a chamber or heatreceptacle is placed above the furnace, which consists of two cylinders or cases, one within the other, the interior'one being open at both ends, its lower portion resting upon the furnace, so that the heat therefrom may pass up through it and be radiated into the room; or

' it may pass down the inner cylinder and out through the space between the two, in either of which cases the outer cylinder will be heated to such an extent as to cause any substance placed upon its upper or outer surface to be heated to a considerable extent. If preferred, however, this chamber may be removed and the heat allowed to pass directly into the atmosphere, it being constructed with slots in the inner cylinder, so that it can be readily applied or removed by passing it over the pipes A and A In making provision for using the gas generated by this implement for illuminating purposes we provide a reservoir, H, which is secured to the platform A at anysuitable point, and has apipe, H, which connects it with the gas-pipe A said pipe H being provided with a cock or valve, H by which the flow of gas to the reservoir can be controlled or shut off at pleasure. Upon the upper end of this reservoir there is secured a pipe, H the outerend of which is supplied with a burner, H, so that the gas entering the reservoir may be burned at that point. p y 4 In order that provision may be made for the generation of gas in the retort A when the implement has been out of use for a considerable period of time, we place in the pipe H a cook or valve which may be closed to prevent the escape of gas from reservoir H, it being allowed to flow into it by opening the valve H By this arrangement the reservoir may be fil led with gas, after which thelast-nam edvalve may be closed, and thus aquantity of gas may be stored up, which may be used in commencing the operation of the implement by opening the valve H and allowing it to pass into the cage, and through it to the point of ignition.

Having thus described our invention, what we claim, and desire to secure by Letters Patent is 1 In an implement for generating gas within itself, to be used for heating soldering-coppers and other substances, the combination of a reservoir for containing the liquid to be converted into gas, placed at such an elevation above the generator that the liquid will flow into said generator by its own gravity, a pipe, A controlled by a valve, A for conducting the liquid to the retort, a retort, A, inwhich said liquid is converted into gas, a pipe, A for conductingthe gas to the point where it is to be discharged, a chamber, B, in'which the gas is burned, consisting of a conical section of perforated metal, and a cage for conducting it to the point where it is ignited, consistin g of a conical section,B, of non-perforated metal and a perforated chamber, B ,all substantially as and for the purpose set forth.

2. The combination of the reservoir A pipe A retort A pipes A and H, and gas-reservoir H, the arrangement being as described,
